of vertical fins, those on caudal very fine and crowded. Cheek, 
opercle and upper branchiostegals scaly, rest of head naked. 
Lateral line rather obscure, complete, of simple tubes. Dorsal 
inserted a little nearer origin of ventral than base of caudal, 
median rays highest. Anal inserted a trifle before origin of 
dorsal and similar. Caudal emarginate. Pectoral a trifle more 
than half way to ventral. Ventral inserted a little nearer origin 
of anal than that of pectoral. Color dark greenish-olive on back, 
lower surface whitish. About 20 abrupt distinct blackish curved 
bands on side, not reticulated. A dark bar from snout through 
eye to opercle, and another from below eye over cheek. Length 
10% inches. Crosswicks Creek at Trenton. 
In life pale or dull olive-brown above, marked everywhere 
with brownish dusky. Upper surface with golden and bronze 
reflections, in some lights coppery. Side with indistinct dusky 
lines sloping down forward. Lower surface white. A blackish 
line from tip of snout to eye and continued behind opercle abave. 
A blackish streak from lower margin of eye down across cheek. 
Lips shaded with dusky. Fins all dull orange-red, dorsal and 
caudal shaded with dull dusky-olive. Iris brownsh-olive-golden 
above and whitish below. A pale median streak from tip of 
snout to upper base of caudal. Several markings of dusky on 
side of head like those on flanks. Inside of gill-opening pearl-

the state, occurring most everywhere, sometimes in shallow 
ditches and pools where its retreat is entirely cut off from other 
waters. It reaches a foot in length and is a good pan-fish. Un- 
like many of our other fishes they always remain perfectly motion- 
less or stationary except for such motion as is required of their 
fins to keep them so. Frequently the glassy goggle-eye may be 
seen before the rest of the body is made out. When taken from 
the water alive they are among the most beautiful colored of all 
fishes but soon fade after death. The color-markings are very
